State (filters, breadcrumbs) etc. should use a separate session key if popup=1

[Toflar]

Description

Right now, if you filter or search (or use the breadcrumb feature to limit tree views) in files, or the DC_Table, this will also affect all the pickers.

This means that when you search e.g. for images ending on *.jpg and then you go and pick some icon that only allows .svg files, you will get the restricted view from before.

Imho, pickers and the "regular" back end session/state should be separated for better UX.
